Worm gearboxes produce high torque at low cost
Worm gearboxes are low-cost options for producing high torque from relatively small electric motors. Their output shaft is at a 90 degree angle to the motor input shaft and higher reduction ratios are obtained compared with conventional gearbox designs. Tony Young, director of electrical and automation maintenance company, CP Automation, explains the benefits of worm gearboxes.
Reports of fieldbuses’ usage disappearing are premature
Although Industrial Ethernet is the clear future direction of the industrial network market it’s also clear that it will be many years before we finally say goodbye to fieldbuses. Michael Volz, General Manager of HMS Industrial Networks GmbH in Germany, says fieldbuses will be popular for many years to come, but that Ethernet will gain ground where it has something extra to offer.
The benefits of active safety for machine builders and end users
Murrelektronik explains how the use of active safety products, connected to a PLC via a fieldbus network, offers advantages for machine builders, system integrators and end users.
Cost-effective development of bespoke panel instrumentation
Ben Savage, PanelPilot Manager at Lascar Electronics, discusses the rising demand from machine builders for customisation of components, and how PanelPilot can help with respect to operator interfaces that are 'bespoke as standard.'
Managing obsolescence and maintaining production machinery
One of the principles regularly quoted by plant engineers is: ‘If it ain’t broke, don’t fix it’. This isn’t always appropriate but when it is, it can relate to machinery that has delivered over 10, 20 or even 30 years with almost total reliability. The question is, what happens when the equipment’s age becomes an issue in itself? Jeremy Shinton of Mitsubishi Electric shares his experience of managing obsolescence and maintaining, updating and replacing tried and trusted hardware in the field of automation technology.
Managing heat in electrical enclosures
Without proper consideration heat can easily build up inside electrical enclosures, triggering damage to the electrical and electronic components within. In addition, such heat can also lead to pressure variances which in turn can draw in moisture and cause problems. Chris Lloyd, Spelsberg UK Managing Director, offers a common-sense overview of the main concerns and their resolution
Multi-fluid hydraulic test facility ensures optimum performance
Designing and manufacturing electro-hydraulic products (pumps, manifolds, valves, controls and systems) requires considerable knowledge and expertise, especially when they are destined for applications in industrial, oil, gas, marine, aviation, civil and military applications where equipment availability is essential. Using advanced engineering techniques such as solid modelling, Finite Element Analysis and Computational Fluid Dynamics, components can now be designed to meet requirements with minimal need for costly and time consuming testing. But what happens when components currently in production are needed to work in new and challenging conditions? This is where in-house testing facilities ensure that each and every product meets the requirements of the application in which it will be operating. Mike Harding, UK Design and Product Development Manager at Oilgear Towler, looks at the benefits of in-house testing for both the manufacturer and the end user.
How to manage quality and traceability for better PLC programs
How can the quality of PLC programs be measured? How is it possible to ensure documentation is always up-to-date? How can traceability be maintained throughout all phases of PLC development projects? This article from Itris Automation explains how a PLC Software Factory provides a solution to these problems.
